UNITED STATES' FRED E. WEBB, OF SYRACUSE, NEW YORK.

SELF-CLOSING sTANcHIoN.

Application led April 16,

T 0 all whom t may concern/:

Be it known that I, FRED E. WEBB, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Self-Clos ing Stanchions; and I do hereby declare the following to be a full, clear, and exact decription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a relatively simple and comparatively inexpensive stanchion for cattle, wherein the closing of the same and the locking thereof in its closed position is effected by the animal in extending the head between the upright or side bars of the stanchion frame, and wherein the introduction of the head of the animal otherwise than in the proper relation to the side bars or uprights of the swinging frame isprevented, so that it is only necessary to adjust the stanchions in their open or receiving positions before driving the cattle into the barn, and the closing of the stanchions will be effected without further effort upon the part of the attendant; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment -ig shown in the accompanying drawings, wherein- Figure 1 is a front view of the stanchion showing the same with its parts in lines in the closed or retaining position and in dotted lines in the open or receiving position.

Fig. 2 is an edge view partly in section.

Fig.V 3 is a detail view in perspective of the connection between one end of the adjustable upright or side bar and the cross head.

Fig. 4 is a detail view of one of the guard hangers. v

.Fig 5 is a similar view of the upper end ofthe'movable side bar or upright to show the means for locking the same yin its closed or retaining position. y

Fig. 6 is a section on the line 6 6 of Fig. 1, and

Fig. 7 is al section on the line 7-7 of Fig. 1. i p

The stanchion consists essentially. of the upper and lower or top and bottom cross heads 10 and V11 which are centrally mount- .ed in a Suitable frese work i2 by ,ineens 9i Specication of Letters Patent.

pivots 13, and side bars or uprights 14 and 15 of which the former is adjustable bodily wlth relation to the upper and lower crossheads, to vary the interval between the side b arg or uprights to suit cattle of diii'erent s1ze`s, and the other is movable relative to the cross heads. and the upright or side bar 14 to permit of the introduction and removal of the head of the stock.

In the construction illustrated the extremitles of the cross heads adjacent to the adjustable upright or side bar 14 are slotted as shown at 16 to receive guide pins 17 carried by. the extremities. of the said side bar or upright, and are notched or provided with a pluralityof seats 18 Jfor engagement by cross bolts 19 which are engaged with the upright or side4 barto secure the latter in the desired position with relation to the cross head. f

The movable side bar or upright 15 is suspended at its upper end from the upper cross head by means of a hanger 20 consisting of a link which is inclined inwardly toward its upper end so that the weight of the bar 15 tends to swing the lower end of the hanger inwardly until the upper end of said bar encountersa stop formed by a shoulder or wall 21 at the inner end of a slot 22 formed in the adjacent end of the upper cross head. The lower. end of the movable side bar is connected with the lower cross head by means of a trip arm 23 adapted normally to occupy a substantially horizontal position when the bar is in a substantially vertical or upright position, and adapted when the upper end of said bar is drawn outwardly to the position indicated in dotted lines in Fig. 1, to swing upward by reason of the movement of the hanger 20, to .assume the dotted line position also indicated in Fig. 1 where its movement is checked by a stop 24 on the lower cross head. The stop -limits the movement of the trip arm to a position which is slightly inward of a vertical plane and it is heldin contact with the stop pin by reason of the upward and outward inclination of the side bar as shownby the dotted lines in Fig. 1 and the tendency 4of said side bar due to the mounting of the hanger to move the upperend of the trip arm toward the center of the ,lower cross head.

`In Athe dotted Aline or open position indicated inFig.- 1 the space between the up- Fghi is suh as to permit Q the@ IYGFQQQQ tion of the head of the cattle, but upon being introduced the neck of the animal encounters the inner surface of the movable side bar at a point below the connection thereof with the lower end of the hanger anda very slight lateral pressure upon the bar is suliicient to throw the trip arm 23 over the center and permit it to drop to the full or closed lines-positionshown in Fig. 1A under the gravital inuence of the side bar due to the swinging movement of the hanger. Thus while it is necessary in order to open the stanchion merely to draw the upper end of the movable side bar 15 outwardly as indicated by the dotted lines in Fig. 1 and whereas said bar will retain this open position by reason of the contact of the trip arm 23 with the stop 24, a very slight pressure or touch applied to the inner surface of the bar `at any point below the pivotal connection vthereof with the hanger 20 is sufiicient to cause said bar to resume its normal o-r closed position indicated in full lines in Fig. 1.

Moreover at its upper end the movable side bar is preferably provided with a dog 25 adapted when said bar is in its normal or closed position to engage a tooth ot a rack 26 carried by the upper side of the top cross head.

Ino'rder that the animal in approaching the stanchion may not insert its head into the space youtside of that deiined by the uprights 14:v and 15 there are employed adjustable guard rods 27 and 28 adapted to be extended in opposite directions respectively from the uprights 14 and 15 when the stanchion is open and to fold into close contact or parallelism with said uprights when the movable bar is in its 4closed position. To this end upper andlower hangers 29 and 30, mounted upon the upright 111 and hangers 31 and 32 mounted ,upon-the upper cross head and the movable side bar 15 are provided respectively for the guards 27 and 2S, the upper hanger 29 being provided also with a crank arm 33 connected by a rod 34 with the upper end of the movable side bar 15, so that when the latter-is swung outwardly to the dotted line position theguard 27v is extended, while carried by said 'movable upright 15 -is a pin 35 for engagement with the hanger 31 to lCorrespo n'dingly extend the guard A28.

rlhus vas the stanchion is opened ashereinbefore described to permit of the entrance 'of the cattle the guards are simultaneously extended and remain in position ,to occupy the spaces lbetween the side bars 4or uprights of the .stan'chions and the sides of the stall until by the action of the animal the stanchion'is'c'losed, whereupon the guards automatically Afold into lpositions close to the in presence of'two witnesses.

cross heads and spaced side bars or uprights one of which is movable relative to the other, a hanger connecting the movable side bar with the upper cross head at a point disposed inwardly of the plane of said bar, and a trip arm connecting the lower end of the said movable bar with the lower cross head for limited inward movement.

`2. A stanchion vhaving upper and lower cross heads and spaced uprights or side bars, one of which is movable toward and from the plane of the other, a downwardly and outwardly inclined hanger supporting the upperend of'said movable upright or side bar from the upper cross head,ay trip connecting the lower end of said upright or said side bar with the lower cross head for inward swinging movement as the upper end of said upright is moved outwardly, and a stop for limiting the inward swinging movemento-f said trip arm to a-position slightly inwardly of a'vertical plane.

- 3. A stanchion having Vpivotal cross heads and spaced uprights or standards whichlare respectivelyv adjustable and movable relative to eachother, theL adjustable standard plane of the other, guard rods for extension in vopposite directions from the planes respectively of said uprights or side bars and connected with the latter by hangers, a crank arm connected with a hanger of the guard rod carried by the upright or stanchion remote from said movableupright or side bar' and connected with the latter, and an'operating pin carried by the movable upright for side bar for engaging a hanger of the guard rod suspended adjacent thereto.
